We spiked these mashed potatoes with wasabi-powder and wow, do they have fantastic flavor. Excellent with roast chicken, pork or beef. 
Ingredients
 
 4 medium potato(es), peeled and cut into large chunks (about 2 lbs)  
 1/2 cup(s) 2% reduced fat milk  
 1 tsp wasabi powder, or more to taste  
 2 tbsp reduced-fat sour cream  
 1 tbsp butter  
 1 tbsp chives, fresh, minced  
 1/2 tsp table salt  
Instructions
Boil potatoes in a large pot of water over high heat until very tender when pricked with a fork, about 15 to 20 minutes; drain and mash potatoes with a hand masher or electric mixer.
Heat milk in a small saucepan over medium heat for 5 minutes; add wasabi powder and stir to dissolve. Add milk mixture, sour cream, butter, chives and salt to potatoes; stir to combine. Yields a generous 1/2 cup per serving.
